With 'Surface phone,' will Microsoft learn from its past marketing mistakes?

One thing that irks many passionate Windows phone fans more than almost anything else is Microsoft's apparent lack of passion for its mobile platform.
Whether there is or was an actual lack of passion from Microsoft is irrelevant. As a company that hoped for a broad consumer embrace of Windows phones, the perception of disinterest from Microsoft was just as detrimental as an actual lack of the same.

If there actually is a Surface phone in the works it should be teased and marketed beginning now.
This should all be handled directly from Microsoft or the appropriate on-board surrogate paid to get the word out.
Goes without saying Microsoft isn't all in.
